THOMAS A. EDISON, OF LIEWELLYN PARK, WEST ORANGE, NEW JERSEY, ASSIGNOR TO EDISON STORAGE BATTERY COMPANY, OF XVEST ORANGE, NEW JERSEY, A CORPO- RATION OF NEW JERSEY.

RECEPTACLE-FILLING MACHINE.

Application filed June 7, 1912.

To all ywhom 'it m ag/ concern Be it known that I, THOMAS A. Entsch', a citizen of the United States, and a resident of Llewellyn Park, lVest Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improven'ients in Receptaclelfilling Machines, of which the following is a description.

In my improved alkaline storage battery, the negative electrodes consist of plates or grids of nickel plated steel having rectangular openings therein, in which are held Hat perforated pockets of nickel plated sheet steel containing compressed therein active material consisting principally or e'ntirely of electrolytically active iron or iron oxid.

My invention relates generally to machines for filling receptacles and is designed particularly for filling and compressing active material into pockets for use in my improved battery, the material heilig fed into open ends of the pockets. My invention may also be Vembodied in apparatus for filling tubes or receptacles of other forms, and in some respects is an improvement in the apparatus described in my prior Patent No. 936,433, dated October l2, 1909.

The principal object of my invention is to provide an improved machine of this type by which small incren'ients of active material will be intermittently supplied to a number of flat pockets; a uniform pressure will be applied to each increment so fed; the feeding and pressure operations for the respective pockets will be independently arrested when the material in the corresponding pockets reaches a predetermined level; and in which provision is Iliade for automatically arresting the operation of the machine when all the pockets have been filled to the predetermined level, whereby all the pockets will be substantially uniform as to the weight of active material carried, and as to the density and molecular' condition of such active material so that the resulting electrode elements may all be of a standard size and capacity.

Another object of my invention is to pro vide an improved apparatus, the use of which will greatly expedite and cheapen the operation of filling the pockets for storage battery electrodes.

ieiom ai the hopper., one oi which shai'is is adapted to be as shown in' a plnrnlitv inde p material at any time within the pockets. This result is accomplished by .the following construction: Each plunger' is formed with a lower tamping portion 4T, adapted to enter the corresponding pocket 10, and to the upn per end of the tamping portion is suitably lattached a weighted portion 18, loosely f1tting in the guide 9 and provided with a ratchet toothed rack 49. The rack 49 is adapted to be engaged by the teeth formed on a. drum 50 carried by the operating shaft 36; an opening being provided in the guide 9 through which a portion of the drum pro jects as shown in Fig. 5. The drum 50 is preferably formed by a plurality of disks 51 corresponding in number to the plunger-s 46, the disks being keyed to shaft 3G and suitably secured against longitudinal movement thereon as by collars 52 and each disk is provided with the same number of ratchet teeth 53 on a portion only of its periphery. The disks are so secured to the shaft 3G that the toothed portions thereof will occupy the same relative angular positions with respect to the shaft. The racks 49 are sufficiently extended so as to be engageable by the teeth on the respective disks 51 at any position which may be occupied bv the plunger-s within the pockets to be filled, so that each plunger' will be elevated for a distance substantially corresponding to the number of teeth on the respective disk 51 and be allowed to drop when the teeth separate, always from substantially the same height above the material within the pocket so as to apply to the same a substantially constant tamping pressure. The teeth which form each rack 49 are so located that when the corresponding plunger 46 is in its lowest position the upper part of the rack will be in position to be engaged by the teeth on the respective disk 51, and as the plunger 4G in performing its tamping operations occupies positions which are more and more elevated, the teeth of the disk 51 will eventually engage the teeth which form the lower part of the rack 49, the number of the rack teeth being considerably greater than the number of teeth on the corresponding disk 51. It will be apparent thatI in the operation of elevating the plungers from any position of rest, considerable concussion is produced by the initial engagement of the first tooth of a disk 5l anda tooth on the correspondingr rack, and should this engagement take place at or near the ends of the teeth, the teeth would be liable to be broken, In order to overcome this objection, the first engaging tooth 54 of each disk 51 has a slightly rounded end and is rcsiliently mounted in a slot 55 in the disk by means of a spring 5E, as clearly shown in Fig. 1G. Each disk is provided with screw 57, the head of which cooperates with ay shoulder 58, formed on tooth to limit its outward movement. The

remaining teeth of the disks 51 may conveniently be formed integral therewith. Therefore, should the end of tooth 54 engage with the end of one of the rack teeth, the tooth 5l would be pressed inwardly against spring 5G, and slide over th. rack tooth to engage the next rack tooti s will be evident. The operating shaft 3G is suitably driven, as by gearing 59, from the main shaft (30. Un the main shaft GO, supported in bearings on one of the standards 2 and a bracket G0 secured to the standard, are mounted a fixed pulley G1 and a loose pulley 62 adapted to be driven by a belt 63. rl`he position of the belt 63 is controlled by a belt shifter 64 slidingly mounted on the frame of the machine, and a spring 65 tends to maintain the belt shifter and thereby the belt 63 in a position in which the belt engages the loose pulley G2. The operating means is preferably designed so that increments of material will be fed to the pockets only as the plungers are being elevated and the openings in the hopper 26 will be closed by the feeding fingers Q8 at all other times. Preferably the arrangement is such that each increment of material fed to any pocket is subjected to but a single tamping pressure before the feeding of the next increment thereto, but obviously this arrangement may be varied so as to apply two or more tamping pressures to each successive increment. if desired.

Owing to variances in the increments of material fed to the pockets and to slight variances in the tamping pressures applied by plungers 46, due to an occasional slippingr of a' first engaging tooth 54 over a rack tooth. the rate of filling the pockets is not exactly uniform, and the material in some pockets reaches the desired level before itdoes iu others. It is therefore desirable to provide for independently disconnectinfir the respective feeding means and operating means and for independently holding the respective plungers in inoperative position with relation to the operating means upon the disconnection of the corresponding feeding means. livotally mouuted on the tie rod 7 is a plurality of locking members (36, preferably bell crank levers, adapted respectively to cooperate with plungcrs 46, to lock the same in inoperative po sition with respect to disks 51 when the ma terial in the corresponding receptacles has reached a predetermined level, and the plungers are raised to the highest elevation above that level. Springs 67 constantly tend to force the arms G8 of locking members 66 into the path of the plunger-s, but l provide a plurality of latches G9, also preferably formed as bell crank levers, which are adapted respectively to hold the locking members 66 in inoperative position until the respective receptacles 10 have been lilled 79 and, 79

Having now disclosed the nature of my invention, and specifically described one embodiment thereof, what I claim and desire to protect by Letters Patent, is
